I have a limited amount of hand-eye coordination, and this was back when the older systems were just coming out, although I still have them to this day. Nowadays, I can’t imagine how much worse I would do. That’s why I always play/played games like Final Fantasy more, because those used a menu system. And I liked the idea that if you couldn’t beat a boss, you could just go out and raise your level up some more, maybe get some better armor or weapons, and then come back and be successful.
But my sister was really good at Mario Brothers and the like. I watched her play Super Mario 3 many a time and she did beat every single level. But when she was playing to beat the whole game, she would use the flute to skip over certain levels so that she could get to the end faster.
